Points in the Coordinate Plane

NC.6.NS.6 Understand rational numbers as points on the number line and as ordered pairs on a coordinate plane.

a. On a number line: o Recognize opposite signs of numbers as indicating locations on opposite sides of 0 and that the opposite of the opposite of a number is the number itself. o Find and position rational numbers on a horizontal or vertical number line.
b. On a coordinate plane: o Understand signs of numbers in ordered pairs as indicating locations in quadrants. o Recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes. o Find and position pairs of rational numbers on a coordinate plane.

Polygons in the Coordinate Plane

NC.6.G.3 Use the coordinate plane to solve real-world and mathematical problems by:

Drawing polygons in the coordinate plane given coordinates for the vertices.
Using coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate.
